If you use eBay, change your password. That's the message from the company after hackers broke into the online retail site and now have customer names, passwords, email addresses and other sensitive information.

The online marketplace says there is no evidence financial information was stolen, but if you are one of the 145 million people with an account on eBay... Some of your personal information, like your date of birth and address, could be in the hands of hackers, but there are things you can do to ward off hackers, according to Chelsea Maguire with the Better Business Bureau.

"It's very important that people change their passwords regularly, we often just get very used to it and we don't want to try to remember something new but when you do change your password regularly it reduces your risk of any hacker going through and find that information," Maguire said.

If you're changing your password, make it something difficult to thwart hackers.

"Simple numbers, your child's birth date, name, those are easily guessed and found, make sure it is very complicated, has uppercase, lowercase, numbers and symbols," Maguire said.

If you want to be extra cautious change your password every month.

"You should have different passwords for different sites, one way to do it is to have a complicated password but maybe use different versions of it, numbers at the end," Maguire added.

Also be careful about what types of credit cards you use when buying things online. Always use credit cards instead of debit cards as there's more fraud protection. As for storing card information online, Maguire said if you don't feel comfortable don't do it and type out your card's digits every time you make a purchase.

"There is always going to be a risk when using online sites for purchasing items, people shouldn't be afraid but they should use caution," Maguire added.

eBay also owns the electronic payment service PayPal, but the company said that PayPal was not compromised as it's information is stored separately on a secure network and was untouched by the data breach.
